The Linux Foundation Kubernetes Application Developer CKAD Free Dumps 2023

1. CORRECT TEXT





Task

You have rolled out a new pod to your infrastructure and now you need to allow it to communicate with the web and storage pods but nothing else. Given the running pod kdsn00201 -newpod edit it to use a network policy that will allow it to send and receive traffic only to and from the web and storage pods.

2. CORRECT TEXT





Context

As a Kubernetes application developer you will often find yourself needing to update a running application.

Task

Please complete the following:

• Update the app deployment in the kdpd00202 namespace with a maxSurge of 5% and a maxUnavailable of 2%

• Perform a rolling update of the web1 deployment, changing the Ifccncf/ngmx image version to 1.13

• Roll back the app deployment to the previous version

3. CORRECT TEXT





Task

Create a new deployment for running.nginx with the following parameters;

• Run the deployment in the kdpd00201 namespace. The namespace has already been created

• Name the deployment frontend and configure with 4 replicas

• Configure the pod with a container image of lfccncf/nginx:1.13.7

• Set an environment variable of NGINX__PORT=8080 and also expose that port for the container above

Task:

The pod for the Deployment named nosql in the craytisn namespace fails to start because its container runs out of resources.

Update the nosol Deployment so that the Pod:

5. CORRECT TEXT





Task

A Deployment named backend-deployment in namespace staging runs a web application on port 8081.

6. CORRECT TEXT





Context

A container within the poller pod is hard-coded to connect the nginxsvc service on port 90 . As this port changes to 5050 an additional container needs to be added to the poller pod which adapts the container to connect to this new port. This should be realized as an ambassador container within the pod.

Task

• Update the nginxsvc service to serve on port 5050.

• Add an HAproxy container named haproxy bound to port 90 to the poller pod and deploy the enhanced pod. Use the image haproxy and inject the configuration located at /opt/KDMC00101/haproxy.cfg, with a ConfigMap named haproxy-config, mounted into the container so that haproxy.cfg is available at /usr/local/etc/haproxy/haproxy.cfg. Ensure that you update the args of the poller container to connect to localhost instead of nginxsvc so that the connection is correctly proxied to the new service endpoint. You must not modify the port of the endpoint in poller's args . The spec file used to create the initial poller pod is available in /opt/KDMC00101/poller.yaml

7. CORRECT TEXT





Context

You have been tasked with scaling an existing deployment for availability, and creating a service to expose the deployment within your infrastructure.

Task

Start with the deployment named kdsn00101-deployment which has already been deployed to the namespace kdsn00101 . Edit it to:

• Add the func=webFrontEnd key/value label to the pod template metadata to identify the

pod for the service definition

• Have 4 replicas

Next, create ana deploy in namespace kdsn00l01 a service that accomplishes the following:

• Exposes the service on TCP port 8080

• is mapped to me pods defined by the specification of kdsn00l01-deployment

• Is of type NodePort

• Has a name of cherry

8. CORRECT TEXT





Task:

A pod within the Deployment named buffale-deployment and in namespace gorilla is logging errors.

1) Look at the logs identify errors messages.

Find errors, including User “system:serviceaccount:gorilla:default” cannot list resource “deployment” […] in the namespace “gorilla”

The buffalo-deployment ‘S manifest can be found at -/prompt/escargot/buffalo-deployment.yaml

9. CORRECT TEXT





Context

A project that you are working on has a requirement for persistent data to be available.

Task

To facilitate this, perform the following tasks:

• Create a file on node sk8s-node-0 at /opt/KDSP00101/data/index.html with the content Acct=Finance

• Create a PersistentVolume named task-pv-volume using hostPath and allocate 1Gi to it, specifying that the volume is at /opt/KDSP00101/data on the cluster's node. The configuration should specify the access mode of ReadWriteOnce . It should define the StorageClass name exam for the PersistentVolume , which will be used to bind PersistentVolumeClaim requests to this PersistenetVolume.

• Create a PefsissentVolumeClaim named task-pv-claim that requests a volume of at least 100Mi and specifies an access mode of ReadWriteOnce

• Create a pod that uses the PersistentVolmeClaim as a volume with a label app: my-storage-app mounting the resulting volume to a mountPath /usr/share/nginx/html inside the pod
